[SOLVED] New Network

I hope someone can help and please be patient because im not that great with computers i try my best.
When i turned my pc on today i got the message new network found and i wasn't really sure what it meant and i paniced and allowed it don't know if it was the right thing to do. I havent changed anything on my pc and I don't have a wireless internet so i dont understand .
Anyway i checked what my ip address was through command prompt ipconfig then i looked at zonealarm-firewall-zones and it has new network and ip address which isn't exactly the same as the one i checked in ipconfig it nearly matches the default gateway whatever that is, except the last number .
Is there something wrong or am i ok?

Edited: to add that 5mins before i got the message the pc was loading up and got stuck on the welcome screen so i turned off by holding the power button in and booted up again then i got the new network message, could it have anything to do with this?
